What is the difference between .tcr and .pfm?

Description: The TCR file format is associated with eBook files specifically used by Psion Series 3 devices. Psion Series 3, a range of personal digital assistants (PDAs) developed in the early 1990s, utilized these files to store and display electronic books (eBooks). TCR files are designed to be compact to suit the limited storage capacities of early PDAs. They contain the text of the eBook, and possibly basic formatting, optimized for the low-resolution screens of the Psion device.; A Printer Font Metrics (PFM) file is a type of file associated with Adobe Type 1 fonts used in Microsoft Windows. It contains metric information about a font, such as character widths, heights, and kerning pairs, which are essential for correctly displaying and printing text. The PFM file works in conjunction with a PFB (Printer Font Binary) file, which contains the actual font outline data.
